JOHN ROYDEN PEIRCE, OF NEW YORK, N. Y.

RECORDING} MECHANISM.

To all whom it may concern Be it known that I, JOHN RoYoEN Parson, a citizen of the United States, residing in. the borough of Manhattan, city, county, and State of New York, have invented new and useful Improvements in Recording Mechanism, of which the following is a specification.

In a previous application, No. 427,859, I have shown and described a machine specially designed as a workmans time recorder adapted to calculate and record wages as well as time; and a card upon which SllCll wages and time were recorded in print and in perforations, and certain advantageous methods of performing such operations. In another application, No. 441,618, I have described an apparatus for recording the movement of a meter or other device of the sort.

The presentinvention provides a machine specially designed for calculating and recording the time and cost of labor expended upon particular pieces of work, or the time and cost of use, of particular machines (such as telephones, for example), and in general the time and cost or the time or cost expended in any operation which may be measured by clocks, meters, machinery registers, andin fact any machines whose'progress is to be recorded. The machine ofthis invention is similar in various functions and mechanisms to the machines illustrated in the applications above referred to. It is common in factories and work-shops to keep a time-book or similar record showing for an individual job the amount of time spent by one or more workmen on such job, from which the cost of labor on the job is subsequently determined according to the wages of'the workmen employed. It is common also in long-distance telephone offices to use time-stamps for recording the time of beginning and ending a message, or, in some cases, recording the elapsed time, and similar recording systems are in use in various businesses. The particular machine hereinafter described is specially designed for keeping a ecord of the cost of labor or any other item which may be measured in units of time. Preferably a card is used which is put into the machine and subjected to the operation of the latter at the beginning and again at the end of a. continuous interval of work upon the job during a day. The first operation on the card may record the time of beginning work. Preferably however it records the money Specification of Letters Patent.

value of such time, either with or without the time 'in hours and minutes; the record being perforated to indicate the amount (of money and of time) according to a determined system of perforations, and being also typewritten or not on the card as desired. The second operation on the card makes a record of the elapsed time either in card may be used to control the operation of a listing machine in which a number of similar cards relating to the same job cause the machine to make a list of all the items of cost of such a job. In this listing machine various other cards, for showing the cost of -material, the cost of freight, etc., perforated according to a system similar to that used in the machine of this invention, would'be used in connection with such card. Such a listing machine "would be preferably arranged to take ofi subtotals and grand totals,

and might make carbon or other duplicate copies for use in different departments, and

would be arranged to take only the record of elapsed time from the cards; forming in this way a very important machine in a shop using the time-recording machine of this invention.

Various other advantages of the invention are referred to in detail hereinafter.

The accompanying drawings illustrate embodiments of the invention.

shaft and connected mechanism.

Referring to the embodiment of the invention illustrated, the casing of the machine contains a front portion A carrying the card pocket B, and a rear portion 0 carrying the clock and'intermediate mechanism, the clock D being preferably mounted horizontally or approximately so on he top of the casin The hand shaft E projects at the side of the machine and carries a handle F by which it is operated. At the beginning of a jobv a card is introduced as far as it will go into the pocket B, and the handle F is pulled and allowed to return, and the card is withdrawn. The same operation is repeated at the end of the job or of the days work on that job, using the same card as for the first operation.

0ards.Before use the card is as shown in Fig. 2, containing a number of controlling perforations at the sides. After the first operation it is as shown in Fig. 3, perforated according to the time and to the amount of money represented by such time at the particular rate selected, and containin also a perforation for controlling its p0- sitlon at the next operation. After the second operation its appearance is as in Fig. 4, where it contains a second set of perforations, representing the elapsed time in hours and minutes and also in dollars and cents, and is printed to indicate the same items.

The card G contains originally various printed points of information and direction, as shown, and these may be of course varied according to the system used in the shop. The card may be perforated to convey this information to the listing machine in which it is subsequently to be used, or the information may be written on in pencil by the workman himself. The card is provided with a number of spaces H, numbered respectively 1, 2, 3, 4., 5 and 6, for determining the rate of charge per hour, any desired one of these spaces being punched so as to obtain for example the third rate. The card is also provided in the beginning with pairs of setting holes J for determining the accurate setting of the card in the pocket in proper position relatively to the punches and feeling pins hereinafter referred to. The cards are preferably supplied in different colors with different rate holes already punched in them, and the different grades of men could use difierently colored cards; thus insuring in a simple way the charging of the cost at a correct rate. In cases Where this is not possible it will generally be necessary for the foreman to give the workman the card perforated with the correct rate. Or the numbering of the cards may be such as to indi cate which rate space is perforated. Thus cards numbered between 1 and 100 might be used by four-dollar-a-day men; between 1000 and 2000, five-dollar-a-day men, etc.

In this case the employee would simply sewhen this arrangement of rate holes is used.

from that in the cards of another shop.

A simple provision is made for facilitating the selection of all cards relating to a job of a particular number. The cards after being perforated the second time, or at the close of each day, are kept in boxes or drawers like those used in ordinary card catalogues. On one or more edges of the card a series of holes K'is provided, and the job numbers which they represent are printed alongside of them. The foreman when he wishes to identify a card with. a

certain job number, punches the interven ingspace between the hole representing the job and the edge of the card (as for number 108 in the example shown). When the cards are arranged on edge in the tray the running of a needle through the first hole and the lifting of such needle will separate all the cards exceptthose which have had the intervening space between the edge of the card and that particular hole removed. By repeating this through each set of holes consecutive cards for each of the different jobs can be separated in a few moments. To make it practicable for the shop it will be necessary for theforeman to have a key card. In this way it would be unnecessary to print the job numbers on the separate cards. This method of selecting the cards constitutes no part of the invention claimed herein, but is described to make clear the uses of the card.

Fig. 5 shows another arrangement of items on the card by which greater compactness is secured. By reducing the size or the quantity of printed matter the size of the card might be still further reduced.

In fact this as well as the other cards described might always be reduced to a size very little greater than that necessary for the perforations made by the machine.

The card of Fig. 6 differs from that of Fig. 4 only in suppressing the printed amount to be charged against the job, so that it will be diflicult for the workman or any other than the listing clerk to know the amount of money which is charged for the work. The time is shown in hours and minutes so that the Workman may be kept informed on this point. The amount is indicated only in perforations so as to properly control the listing machine in Which the card is subsequently used.

The design of the cards and the arrangement of the various parts thereof and perforations thereon may be substantially varied from those shown. I

The system of pcrfomtiom.Var1ous systems for perforating the cards may be used, and I have described a variety of such sys tems in my previous applications above referred to and others. In the present machine I prefer to arrange the perforations for each numeral in av vertical line, using various combinations of four perforations (Fig. 7) or less as the minimum number which can be used to represent ten different digits, and

arranging these four holes over five different spaces for simplicity in the mechanism. The card is shown ruled in Fig. 4 for the purpose of explaining the-locations of the various parts, but in use it will ordinarily not be ruled. The amount space is incli- 'cated at L and the time space at M. Commencing at the right-hand side of the card, the first, third, fifth and seventh columns represent the numerals 5, 1, 6 and 0 respectively, and these numerals are printed (with the exception of the zero at the left of the amount which is suppressed in the ordinary Writing of numbers) on the line above the perforations and at points between the first and second columns, the third and fourth columns, etc. The first operation on the card perforates the columns N to represent the time. at which the operation is performed. The second operation perforates the columns 0 to represent the elapsed time since the first operation, and prints the numbers corresponding to such elapsed time. The combinations of holes used to express the different numbers will be understood from Fig. 7, which shows openings in the punch-operating plates which avoid the operation of certain punches when the plates are advanced, and which correspond therefore to the unperfora-ted spaces on the card for the same number. The punching plates, as'indicated in plan at P, Fig. 21, have an intermediate open portion, and have solid portions at the ends, which include the two operative spaces at each end of the fivespace combination.

The machine in generaZ.A number of gears are continuously rotated from the clock at difierent rates of speed, and these may be'called the rate mechanisms. There are six such rates (corresponding to the hole spaces H on the card) provided for in the present machine, one being a straight time rate and the others being money rates. When a record is to be made on a card the pulling of the hand lever throws a selected .rate mechanism into gear with the recording 'mechanism. and the recording mechanism is given a movement limited by the rate 'mechanism so as to bring the devices for printed also) to release hammers which drive the printing type against the ribbon and the card. In. the first operation on a card it moves clear to the lowest point in the pocket. A subsidiary punch, however, makes a hole Q, therein, which, upon the next insertion of the card, controls a spacing mechanism which limits the downward movement of the card in the pocket to such a point as to insure the locating of the second series of perforations between the lines of the first series. The spacing mechanism is described hereinafter under Card control at second operation. A- second per foration Q (Fig. l) is made at this second operation, which serves to indicate at a glance that the record has been completed (see hole 17, in punching plate, Fig. 22).

Z0c70-(lri2.-(2)z mcchanism.The movement of the clock is transmitted to the rate mechanisms from a master wheel R (Figs. 8 and 14) which is operated only during earning time. The master wheel is driven by a pinion S on a shaft T, the latter being provided with a gear U (Fig. 10) having pointed teeth, and which is intermittently engaged with and disengaged from an arm or ring V contiimously rotated by the clock and having a tooth TV which is brought into engagement with the gear U during earning time, and moved out of engagement therewith during the noon hour and at the end of the day. The control of this is explained more fully hereinafter under the title Earningtime mechanism.

The motion of the master wheel is transmitted to the several rate mechanisms by gearing whichdrives these rate mechanisms at different speeds. Each rate mechanism comprises a shaft X in fixed relation with the master wheel, and a movable shaft Y containing gears driven from the fixed shaft X and carrying gears which take the motion of the fixed shaft X and impose it upon the recording mechanism at each operation of the machine, the shaft Y for this purpose being shifted from the engagement of its gears with those on the shaft X to engagement of its gears with sectors of the recording mechanism, and being at the end of each operation of the machine returned to maintain engagement with the shaft X. The several shafts X are indicated individually as X, X X X, X and X and the several shafts Y are similarly distinguished as Y, Y etc.

Fig. 14 shows the several shafts X driven from the master wheel R at diminishingrates of speed relatively to each other by gears of appropriate size, which I designate generally as Z, and which are distinguished particularly as X, X etc., these being located between the master wheel R and the respective shafts Y. Y etc.

The motion of each shaft X is transmitted to gears a, 6, etc., carried on sleeves on said shaft, the unit gear a of each group being driven at the same rate as the shaft X, and each successive gear being given, throi'zgh the intermediation of the gears on the shaft Y, a step equal to one-tenth of a rotation for each complete rotation of the gear of next lower decimal place. The gears a, Z), etc., on the shaft X, are given an intermediate movement by quick steps, instead of a slow continuous movement, so as to avoid any difficulty in the registering of the gears on the shafts X and Y with each other when they are brought together. The following description of the parts involved may be readily followed in Fig. 20 by observing that the various parts mounted on each shaft are detailed one by one on the other corresponding shafts in the order X, X X X. This intermediate movement is secured by an escapement on the bottom of the shaft X comprising (see Figs. 20 and 25) a starwheel 0 on the shaft X, which swings an arm cl on a supplementary shaft 0 and thus oscillates an escapement anchor f on the same shaft which permits the step-by-step movement of an escapement wheel 7 which is loose on the shaft X and is pressed forward always by a spring driven by the shaft X: the escapement wheel g being connected with and driving the gear a on said shaft. The gear a on the shaft X drives a gear h (Figs. 8 and 17) on the lower end of a sleeve on the shaft Y, which sleeve i has at its upper end a one-toothed gear or disk 7' which drives a ten-toothed gear or disk 70, on the shaft X, the disk being connected with the gear 6 so as to drive the latter. The gear 6 then drives the gear Z of the second decimal place which is mounted on the shaft Y, and so the motion is transmitted to the end of the gearing. This is a common style of gearing in adding machines and is illustrated more fully in the sectional view, Fig. 30.

Transmitting the motion of the rate mechanism to the recording mechanism.- The gears h. Z. etc., constitute the first set of successivelv higher decimal places carried on the shiftable shafts Y. Said shafts carry also, loosely mounted thereon. a second set of gears m, n of successively h gher d cimal places. the gear m corresponding with the gear h, the gear n with the gear Z, etc. These alternate or intermediate g ars m, n, etc., are designed to impose upon the recording sectors movements correspond ng with the record made at the first operation, and are moved only upon the second operation. At the first operat on on any card the gears 777, n, etc., are held stationarv. For each decimal place there is a p'airof toothed sectors. a lower one. 0. (Figs. 8 and 19) in the plane of the cloclr-drii'en gear. as h. and an upper sector 7? (Fig. 16) in the plane of the previous-reading gear, such as m. .At each operation of the machine the gears h and m are thrown into engagement with the sectors and p respectively.

At the first operation on any card there is no previous reading, and the previousreading sector p and its gear m are held stationary at the zero position as shown in Fig. 18 (by the stop pins 51 carried on links 52 connected to sectors 10 and stopped by plates 54, Fig. 16, which are initially looked as hereinafter described under Previous-reading mechanism). The previous-reading gears, as m, are provided each with a stop g (Figs. 17 and 18) carried on a slide 7 which slides inward and outward on a hub s which is fixed on the previous-reading wheel m, and which therefore rotates with said hub and wheel. Springs t are provided tending normally to throw the slide 1 to the operative position shown in Fig. 19 in which its stop 9 lies in the circular path of a zero stop at on the adjacent face of the corresponding clock-driven gear h. The slide 1' is preferably extended at its outer end and notched so as to normally engage the sleeve v on the fixed shaft X and thus prevent rotation of the gear m.

The amount registered by each of the clock-driven wheels h is represented by the distance which its zero stop at has advanced (clockwise looking downward on Fig. 18) beyond the point at which it would come into contact with the stop q on the slide above it if the latterwere moved to its inner operative position. Ordinarily, however, the parts stand in the position of Fig. 18, and the slide 0" is moved outward by reason of the engagement of. its inner end against the sleeve o, and its stop 9 is beyond the circular path of the zero stop u of the clockdriven wheel; so that the latter rotates freely. When the movable shaft Y has been shifted to bring the gears h, etc., into engagement with the sectors 0, the latter are turned by springs (84, 85 Fig. 20', as hereinafter described) and carry with them the gears h, etc., out of engagement with clockdriven gears a, etc., and rotating the latter forward (through a distance which is necessarily the complement of the true clock reading) until their zero stops a strike the stops g, the latter being then in the paths of the several zero stops u. The plates 1' and stops u are held against rotation by reason of the engagement of the wheels m with the gears 72, which are locked, as stated above. The sectors 0-f\u1s receive a movement limited to the number of steps which each of the clock-driven gzirs has to advance in order to reach its next zero position. By reason of the reversed arrangement of the types (and likewise of the punches) as indicated in Fig. 29, this complementary movement of the sectors 0 brings into recording position the number representing the actual position of the. clock. The number represented by the several digital'sectors o is the number recorded at the first operation upon a card.

In the second operation of my card, the sector 0 engages the clock-driven gear lb and turns it until its lug u strikes the corresponding lug g on the slide 7' as in the first operation; and, the sector p having been released by the inward movement of one or more of the feeling pins 43, Fig. 16, and being permitted a limited movement corre sponding to the present reading, as hereinafter described, under Previous reading mechanism, the gears m and slides '1" are also released, and the sectors 0 which carry the type are further advanced to the full extent of the present reading. It is desired to subtract the previous reading from the present reading of the clock-driven gears, and this subtraction is very simply performed by allowing the spring to impress upon the recording sectors o-not only the amount of movement represented by the original position of the clock-driven gears, but an additional movement in the same direction and equal to the complement of the present clock reading. The reason for this rule is apparent upon considering the devices shown in Figs. 18 and 19' and the reverse arrangement of the types shown in Fig. 29. These types are carried only upon the lower sector 0 of each pair of sectors 0 g). The sector 0 engages the lower gear 71; and the sector ;0 engages the upper gear on. The type-carrying sector 0 will advance (in the direction of the arrow, Fig. 29) at each operation as far as the gear h with which it is engaged, will permit. Before a first operation on a card the gear h is found with its stop u advanced to a certain position corresponding to the time indicated by the clock. The shaft Y carrying the gear is then shifted toward the sectors and the gear h, in its time-indicating position, is brought into engagement with its sector 0. The movement of the shaft Y toward the sector has released the slide 1- and allowed it to shift to bring its stop 9 in the circular path of the stop a of the gear h. When the sector 0 is then released its springs turn it in the direction of the arrow and the extent of its movement is limited by the stop it striking the stop q. Its actual movement is then a number of steps which is the complement of the actual time at which the gear it stood; and by reason of the reversed arrangement of the types this complementary movement causes the printing of the correct number. When the number has been printed the segment 0 is reset while still engaging the gear h, so that the gear h isturned back to the position corresponding to the time, that is to say the position to which it had been set by the clock shaft before the recording operation. If the clock had moved to the third hour then the stop u on the gear 7:. would standthree steps ahead of the stop 9. In this'position of the gear it, the shaft Y carrying the same is shifted back to bring the. gears into engagement with those on the shaft X.

During the following intermission the gear h is further advanced by the clock, the gear m being stationary. At the second operation on the card the gear b will be found further advanced than at the first operation. Whenthe shaft Y is moved toward the sectors, if the sector p remained locked and its gear m stationary the plate 1" and its stop 9 would be found in the same position as for the first operation so that the movement of the gear 71. would be merely the complement of the time at which it stands or the number of steps wh ch it has advanced from the zero position. But on this second operation the plate 1- does not remain stationary. The sector p is unlocked and is allowed to move a distance equal to the reading at the first operation. If the reading at the first 5; operation was 3 the plate a" and stop g are allowed to move forward three steps as shown in Fig. 19. Themovement of the gear 71, therefore, would be three steps, or the amount of movement represented by the position of the clock at the first operation, in addition to the regular movement of the gear h which is the complement of its pres .ent reading. By comparing these movements with the numbers indicated in Fig. 29 it will be seen that the total movement of the sector 0 will bring that type into position which corresponds to the difference between the two times.

Thus if the present reading of any clockdriven wheel is 9, and the previous reading made on the card at its first operation is 3, the difference should be 6; and this is obtained by adding 1 (the complement of the clock reading 9)' to the previous reading, 3, giving a total of four steps to the recording mechanism. The series of numbers is so arranged that these four steps carry the recording mechanism to the number 6 of the first series. Only the 6 is recorded, the successive decimal places of the mechanism being disconnected from each other so that there is no carrying of the additional 1 in the tens place to the next higher recording mechanism.

To subtract a larger from a smaller number, as a previous reading of 9 from a present reading of 3, the operation is substantially the same; that is we add the complement of 3. that is, 7, to the 9, and obtain 16; and moving the recording mechanism sixteen steps causes the recording of the proper difference, 4 by reason of the illustrated arrangement of the series of numbers. Here the recording mechanism passes beyond the first set of digits from 9 to 0,

income and this is always true in subtracting a larger from a smaller number; while the reverse is always true in subtractin a smaller number from a larger num er. Where the subtrahend is larger than the minuend it is necessary to subtract 1 from the next higher decimal place, and this is effected by the circumstance that the recording mechanism is shifted beyond the first series of digits, as hereinafter. described in detail.

Near the end of each operation before the sectors are disengaged from the gears, the sectors are returned to their starting position, returning the clock-driven gears to their starting position and the previousreading gears and stops q to their zero position, and the shafts Y are then thrown outward again to bring the clock-driven gears into engagement with the gears a, 6, etc., on the fixed shaft X, so that they take up the movement of this shaft at the same point where they leave it off at the beginning of the operation.

Time-recording mechanisam l or recording the time in hours and minutes, a second group of recording devices and sectors is arranged above those for recording the amount in dollars and cents. The upper set of four recording devices shown in Fig. 8 is arranged for hours and minutes, and the lower set for dollars and cents. It is necessary therefore to provide a series of clockdriven wheels for the sectors of this timerecording mechanism, and such gears and the controlling mechanism therefor are indicated in Fi s. 15 and 25. The fixed clockdriven shaft X beside-s carrying wheels a, 2'), etc., for the lower amount-recording mechanism, carries an upper set of clock driven ears a b actuatin ears 72. Z carformed on a plate which is completely circular, and as shown in Fig. 20 carries on its upper face a double series of types 12 adapted to be brought by the rotation of the plate successively in line with a ribbon 13 so as, when struck by a hammer 14, to print upon a card carried in the pocket of the machine. On the under side of the plate 0 (Figs. 8 and 21) are carried the series of punching blocks or plates P previously described. The types 12 and blocks P are turned together to bring the proper type and block into register. The blocks thereafter actuate the punches by a forward movement of the plate 0, but the types do not print until struck by the hammer 14. In the horizontal plane of the several blocks P carried on the under side of each one of the plates or disks 0 is carried a series of punches supported in a plate 16 and bars and adapted to be forced through the paper in various combinations by the different blocks P according to the various combinations of sockets produced by varying the positions of said blocks P as shown in Fig. 7. Each movement of a block through one step, a distance corresponding to that between centers of successive punches, varies the combination of punches which shall be operated on the advance of the block.

The punches 15 pass through holes in the inner wall 16 of the card-pocket B, and an outer wall 17 is provided having similar perforations for receiving the punches and the feeling pins hereinafter descrlbed. In

Fig. 22 the recording punch holes are shown at 17*, the feeling-pin holes at 17', and the hole for determining the position of the card at a second operation at 17, a punch like 15 being in register with the hole 17 and being actuated at each operatlon of the machine to make the hole 9/ or 9 above referred to. The plate 17 is essential to back the card at the points where it is being perforated. It is preferably made removable, however, by having a base flange 18 which is screwed or similarly fastened to the base of the machine, and is preferably also stiffened by side walls 19. By removing the backing plate 17 for the card, the ends of the punches are made accessible for sharpening or the like.

Preferably the punches 15 are earned in a frameconsisting of a number of cross-bars 20 (Figs. 8, 21, 26 and 27) extending between the horizontal planes of the ClISkS and in the planes of the punch-operating blocks P. These cross-bars 20 are all fastened together at one end by sleeves 21, and are normally heldin place by a rod 22 at one end threaded through the sleeves 21, and a rod 23 at the other end passing through holes in the free ends of the cross-bars 20, the rods 22 and 23 being passed down through the top plate and screwed into the bottom plate. This construction has the advantage that by first withdrawing the rods 22 and 23 the comb or frame consisting of the cross-bars 20 held together by the sleeves 21 and carrying all the punches 15, can be withdrawn in a lateral direction without interfering with the other parts of the mechanism. Figs. 26 and 27 indlcate the construction. Such a frame carrying all the punches in exactly their desired positions and easily separable from the machlne, 1s of great advantage in permitting the ready repair or replacement of one or more of the punches without danger of disturbing the others or of disturbing the rest of the machine.

The proper punch-actuating block P and type 12 having been brought to operative position, the continued movement of the handle forces forward the frame carrying the shaft 24 upon which the various disks are mounted, and thus punches the desired combination of perforations in the card. The forward movement is effected as follows: The shafts X and Y and the shaft 24 are all carried between an upper plate 25 and a lower plate 26. The master wheel R which drives the several shafts X is mounted on the upper plate 25, but the pinion S by which the master wheel is driven is mounted in a separate frame above the plate 25, so that the master wheel may be carried forward with the plate 25 upon which it is mounted and with the several mechanisms inclosed between the plates 25 and 26. (these plates being firmly connected to each other by the shaft described and by additional tie-rods or bolts at various points). See Figs. 8, 14 and 20. At the rear the plates 25 and 26 are connected to each other by stiff uprights 27 which in the continued rotation of the hand-shaft E are engaged by pins 28 projecting laterally from arms carried on said shaft so as to press said uprights and the entire frame forward against the resistance of the strong springs 29 connected to uprights 30 at the rear and holding the frame carrying the recording mechanism normally in its retracted position against said uprights.

The hammers for actuating the type operate on a principle familiar in adding machines, of the Burroughs type for example. The hammer 14, Figs. 20 and 21 is normally retracted by a spring 31, beingpivoted at 32 and being actuated with a sudden movement by a flange 33 overhanging the forward arm of the hammer, and which is mounted on a. follower 34 pivoted on the same pivot 32 as the hammer. The member 34 with its flange 33 is normally restrained by a resetting pin 35, which however at each opera tion of the machine moves out of engagement with the member 34 so as to allow the strong spring 36 of the latter to swing the flange 33, and with it the hammer, forward.

The resetting rod 35 which serves for all the hammers is connected by suitable arms to the shaft 32 by which it is actuated. This shaft runs through the top plate 25, and at its upper end has an arm 32 which connects with a link 32 the opposite end of which passes around an eccentric 32 on the shaft 24 of the several sectors, and this eccentric is turned in the forward movement of the plate and shifts in a direction to release the several hammers, and in the rearward movement in a direction to reset the hammers.

A stop 37 is provided for preventing the operation of the hammers when the card is put in the machine the first time. The stop 37 is pivotally mounted on a shaft 38, and has an arm 39 connected to a spring 40 by means of which the stop 37 is held as far forward as possible. The shaft 38 is fixed; that is to say, does not partake of the forward movement of the disks in the making of a record. The shaft 32 which carries the hammers and followers 34, however, does partake of such forward movement. Such movement, however, is not suflicient normally to carry the end of the arm 34 beyond the stop 37 so as to permit the operation of the hammers.

On the second operation for the same card the stop 37 is turned inward slightly so that when the hammers and followers are brought forward the follower 34 will carry its forward end clear of the stop 37' and will be free to actuate its hammer. The movement of the stop 37 is effected by meansof an arm 41 carried on the lower end of the shaft 38 and projecting toward the center of the machine. This arm is shown in section in the bottom of the machine in Fig. 8, and is in the path of a striker 42 (by the action of the card on a link 118 carrying said striker 42, as hereinafter described under Card control at second operation) which moves to the rear when a card is introduced into the machine which has been previously operated on. The striker 42 throws the inner end of the arm 41 inward and turns the shaft 38 and stop 37 to carry the latter to a point where it.no longer locks the follower of the hammer.

The same stop 37 is used to prevent the striking of zero for the highest decimal places; that is to say, to suppress the zeros in decimal places higher than the number actually printed.

' Previous weeding mechanism.F0r impressing upon the previous-readingsectors p a movement corresponding to the previous reading as perforated in the card, mechanism may be employed similar to those described in my application No. 427,859 above referred to, or in my application No. 479,189. The mechanism is simplified however by the use of the preferred system herein described in which four holes are punched in five spaces on the card. The middle space is not used. Consequently the feelers 43 (Fig. 16) are arranged in groups of four occupying the first two and last two of five horizontal spaces. These feelers are pressed forward by springs when the card is inserted, and one or more of the feelers enters and passes through the card in accordance with the combination of holes which the group of feelers meets. The combination of feelers which moves through the card determines or limits the movement which the sector p receives under the influence of the spring which tends to turn it. The several feeling pins 43 of each group are connected to slides 44 which are bent to pass around the central shaft 24 and which are connected at their rear ends to the rear ends of springs 45, the forward ends of said springs being connected to an upwardl projecting flange 46 on a frame 47 of whic there is one supported above each of the previous-reading sectors and fixed relatively thereto. In making a record the frame 47 moves forward and conveys the necessary yielding forward pressure to the individual slides 44. The backward movement of the slides is effected b means of an arm 48 lying in the same p ane with the frame 47, the arms 48 for the several previous-reading mechanisms being fixed on a common shaft 49 by which they are actuated. The slides 44 are provided with pins 50 adapted to be engaged by the rear edge of the arm 48 to withdraw the slides. The shaft 49 is connected at its upper end (Fig. 14) to an arm 49 and a link 49 which runs downward through the plate 25 and is connected just below that plate to an arm 28 (Fig. 15) which swings forward whenever a card is properly placed in the machine, as hereinafter described in detail, and thus releases the slides which carry the feeling pins. A compound control is called for in order to secure the desired movements of the sector p from the four slides 44. The slides 44 are normally stopped by means of a. pin51 carried on an arm 52 which is pivoted to the sector 2; the pin 51 being caught and held by a shoulder on a main controllin arm 53. The controlling arm 53 is rovided with a stop-arm 54 which is provi ed with a series of stops adapted one after another to engage the first supplementary stop-arm 55 as the latter is swung outward about its pivot 56. The first supplementary stop-arm 55 furthermore is pivotally mounted at 56 upona second supplementary stop-arm 57 which is pivoted on the shaft 24 and whose movement carries with it the first supplementary arm 55 as well as the main stoparm 53. The arm 55 is held inward upon the arm 57 by a sprin 58.

The movement of t e first supplementary stop-arm 55 about its pivot is effected by means of pins 58 projecting upward from the slides 44 andengaging the inner edge of the arm 55. The movement of the second supplementary stop-arm 57 is determined by stops 59 projecting downward from the slides 44 and adapted when sufiiciently advanced outwardly to lie in the path of one of the shoulders 60, 61, 61 on the arm 57, so as to limit the amount of forward movement of said arm. The several pins 43 move forward through the card to different distances, and the slides 44 with them. Each slide.moves forward always until a stop 61 on the under side of its rear end strikes the outer edge of the fixed frame 47.

thereby to the first supplementary stop-arm 55, since the pins58" carry said arm forward a distance corresponding to the movement of the pin or pins. 1

The stop-arm 57 is held in its normal position by a light spring 62 fastened .to the frame 47, and is stopped by a stop-pin 63.

The sector p is supported from a central hub by means of arms 64 and 65, the latter being provided with an upward flange 66 lying in the plane of the main stop-arm 53. When a subtracting operation of a larger from a smaller number is effected and it is necessary to reduce the number in the next higher decimal place by 1, this is efiected by increasing by one step the forward movement of the previous-reading'sector p of the next higher decimal place. The space between the flange 66 on the arm which carries th'esector p and the stop-arm 53 which limits the movement of said sector is normally one unit. When such a carrying operation as has just been referred to is to be performed, the arm 52 is pulled outward by means of an arm 67 on a shaft 68 and having a roller lying in a slot in said arm 52. This withdraws the pin 51 from en- *gagement with the arm 53 and allows the sector p to move forward one more step than would normally be the case, and until the flange 66 strikes the stop-arm 53 and prevents further movement of the sector. The several sectors are preferably guided in their horizontal planes by spacers or guides 69 held in place by rods 70 connecting the vupper andlower plates which carry the several sectors.

The carrying operation is eflected as stated by throwlng the arm- 67 outward.

. Each of the arms 67 is mounted on the upper end of asleeve on the lower end of which is an arm 71 (Fig. 20) projecting under the plane of the next lower clockcontrolled sector 0. The 4 plate 72 upon which the clock-controlled sector 0 and its types 12 and punch-actuating blocks P ar mounted, is provided on its under side in the plane of a roller carried on the end of the arm 71, with a cam orprojection 75. When the sector 0 moves through a distance corresponding to the first series of ten digits, the forward end of the projection 75 moves just to the point where it engages the end of the arm .71. In" the further movement of the sector corresponding to the second series of digits, the projection 75 presses out the end of the arm 71 and turns the sleeve on the shaft 68, which sleeve is connected in the plane above (Fig. 16) with the arm 67 of the previous-reading sector of the next higher decimal place. Consequently when the types move only through the first series there is no movement of the carrying arm 67 of the next higher decimal place; and when the types of the second series of digits move into operative position there is a movement of the arm 67 in the next higher decimal place. To accomplish thi result the recording mechanism is set to start from a point corresponding to minus one, instead of from a point corresponding to zero. Unless there is a movement of the carryin arm 67 therefore the number recorded will be one less than that which would be recorded if there were no carrying operation; and whenever the number in the next lower decimal place is obtained by subtracting a smaller from a larger number, that is to say, whenever the second series of types comes into play, an additional step forward is given to the record mechanism of the next higher decimal place to compensate for the original minus-one position of the parts.

The several sectors are reset in their starting positions (Figs. 16 and 17) by a rod 76 which is supported at its upper end upon an arm 105 free to turn on the shaft 24 and adapted to be engaged by a pin 104 on a loose arm 77 which is connected by a spring 78 to the fixed wall 79 at the rear of the pocket, and connected also by a flexible steel band (made in two connected parts 80 and 81, Figs. 15 and 24) which runs over a guide pulley 82 at the rear of the machine with a sector 83 on the hand-shaft E. When the hand-shaft is turned backward, the ribbon 81 is wound on the sector 83, and by the connection at its upper end turn the arm 77 and the resetting rod 76 forward to restore the various sectors to their initial positions. When the hand-shaft E is operated in the forward direction, it unwinds the ribbon 81, 80 and releases the arm 77 so that the pring 78 turns the latter and frees the various sectors. Springs such as 84, 85 (Fig. 20) then give to the sectors the forward rotary movements described. These two springs 84, 85 are both connected to th single plate 72, two springs being used for the sake of compactness in vertical dimensions. These springs serve also to giv the previous-reading sector its movement. The

sector 0 engages the clock-driven gear h and turns it until its lug u strikes the corresponding lug g on the previous-reading gear m, and then rotates this previous-reading gear and with it the previous-reading sector 19 to a distance determined by the previous reading, as above described.
